The image shows the first word of the next round key to be "fe af 01 b7" when I believe it should be "d6 aa 74 fd". My implementation is correct for the next answer which includes all the round keys and I also worked it out by hand.
d7 ab 76 fe ^ 00 01 02 03 = d7 aa 74 fd
Rcon(1) = 01 00 00 00
01 00 00 00 ^ d7 aa 74 fd = d6 aa 74 fd
Hopefully this is helpful.
